Invoice Payment Terms Explained: Net 15 vs Net 30 vs Due on Receipt

Invoice payment terms define when and how a client should pay. Choosing the right payment terms directly affects your cash flow, client relationships, and how quickly you get paid. Research from Xero shows that businesses with clear payment terms on invoices get paid up to 2x faster than those without. This guide explains every common payment term, when to use each one, and practical strategies to ensure clients actually pay on time.

What Are Invoice Payment Terms?

Invoice payment terms are the conditions you set for how and when payment is due. They appear on your invoice and typically include:

• When payment is due (the deadline)
• How to pay (bank transfer, online payment, check)
• What happens if payment is late (late fees, interest)
• Discounts for early payment (if offered)

Payment terms are usually agreed upon before work begins — ideally in your contract or statement of work. Including them on every invoice reinforces the agreement and gives the client's accounts payable team clear instructions.

Common Payment Terms Explained

Due on Receipt

Payment is expected as soon as the client receives the invoice. This is the most aggressive term and works best for:

• Small, one-time transactions
• New clients you haven't worked with before
• Retail or consumer-facing services
• When you have high bargaining power

Typical use: Service businesses, retail, small freelance projects under $500.

Net 7

Payment is due within 7 calendar days of the invoice date. A good middle ground between "due on receipt" and longer terms.

Typical use: Freelancers doing recurring work, subscription services, small agencies.

Net 14

Payment is due within 14 calendar days. This is the most common term for freelancers and small businesses because it balances cash flow needs with client convenience.

Typical use: Freelancers, consultants, creative agencies, small service businesses.

Net 30

Payment is due within 30 calendar days. The most widely used B2B payment term globally. Most corporate accounts payable departments are set up to process Net 30 payments.

Typical use: B2B services, consulting, agencies working with mid-market and enterprise clients.

Net 45 and Net 60

Extended payment terms used by larger corporations. These terms favor the buyer and can strain your cash flow, so only accept them when the deal size justifies it.

Typical use: Enterprise contracts, government contracts, large corporate clients.

2/10 Net 30

The client gets a 2% discount if they pay within 10 days; otherwise, the full amount is due in 30 days. This incentivizes early payment — a 2% discount for paying 20 days early equals a 36% annualized return for the client, making it very attractive.

Typical use: Wholesale, manufacturing, established B2B relationships.

End of Month (EOM)

Payment is due at the end of the month in which the invoice is issued. For example, an invoice dated March 15 is due by March 31.

Typical use: Companies with monthly accounting cycles, retainer agreements.

Milestone-Based

Payment is tied to project deliverables rather than calendar dates. Common structures:

• 50% upfront, 50% on completion
• 30% upfront, 30% at midpoint, 40% on completion
• Payment at each defined project phase

Typical use: Large projects (web development, construction, consulting engagements over $10,000).

How to Choose the Right Payment Terms

The best payment terms balance your cash flow needs with what the market and your clients expect.

Consider Your Cash Flow

If you rely on invoice payments to cover monthly expenses, shorter terms (Net 7 or Net 14) are essential. If you have a financial buffer, Net 30 may be fine and opens up more client opportunities.

Consider Your Industry

Industry norms matter. Construction uses progress billing and Net 30. Freelance creative work often uses Net 14. Enterprise B2B defaults to Net 30 or Net 60. Going against industry norms can feel unusual to clients, so understand what's standard in your space.

Consider the Client

New clients deserve shorter terms until trust is established. Long-term clients with a reliable payment history can earn more favorable terms. Large corporations may insist on their standard terms (often Net 45 or Net 60) — factor this into your pricing.

Consider the Project Size

For large projects, milestone billing protects both parties. You don't carry the financial risk of months of unpaid work, and the client doesn't pay the full amount before seeing results.

How to Get Clients to Pay On Time

Setting payment terms is only half the battle. Here's how to ensure they're respected:

Include payment terms on every document. Contract, proposal, invoice — every document should state the terms consistently.

Send invoices immediately. Invoice the day you deliver. Every day you delay sending the invoice is a day added to your payment timeline.

Make payment easy. Include a direct payment link on every invoice. Clients who can pay with one click pay faster than those who need to set up a bank transfer. InvoiceQuickly automatically includes payment links on every invoice.

Send reminders before the due date. A friendly reminder 3 days before the due date catches invoices that might otherwise slip through the cracks.

Enforce your late fee policy. State your late fee terms clearly and apply them consistently. Even if you waive the fee as a goodwill gesture, sending the notice shows you track payments seriously. Use our late fee calculator to determine the right rate.

Offer early payment discounts. A 2% discount for payment within 10 days costs you very little but can dramatically improve your cash flow.

Follow up promptly on overdue invoices. The longer an invoice goes unpaid, the harder it is to collect. Our payment reminder email drafter generates professional follow-up emails at every escalation stage.

Late Payment Fees: What You Can Charge

Late fees compensate you for the cost of delayed payment and incentivize clients to pay on time. Common approaches:

Percentage-based: 1-2% per month on the overdue balance. This is the most common approach.

Flat fee: A fixed amount (e.g., $25-$50) added to overdue invoices. Simpler but less proportional.

Statutory rates: Some jurisdictions set minimum rates:

• UK: 8% + Bank of England base rate annually
• EU: ECB reference rate + 8 percentage points
• US: Varies by state, typically 1-1.5% monthly maximum

Always include your late fee policy on your invoices and in your contracts before it needs to be enforced.
